I've loved the music from way back when but tonight listening (and watching) this on PBS really moved me to another level. Josh Grobhan ---- what an amazing voice! The ensemble was fabulous, but Josh stood head and shoulders above the others. Wow, wow, wow!!!! I have the original cast recording. I will dig it out and listen again but I doubt I will hear Josh's amazing rendition.
My one negative comment will be Idina Menzel who sang Florence -- great voice but very discordant to me in this role. She seemed to shout the vocals and it was not pleasant to listen to. Great performance, great music, and think Chess works very well in this format.
